7 Claims. (Cl. 156-914) My invention relates to Windowscreens, and more particularly to screen supported sashoperators that are adapted to cooperate mutually with casement windows of the swinging type and screens associated therewith.

The main object of my invention is to provide a screen frame which is so formed as to permit ;,a sash operator .to be selectively supported on the :screen frame or upon a sash frame, whereby, in either case,.the screen or sash may be adjusted each independently of the other.

Another object is to provide a sash operator which is so; arranged as to be readily mounted selectively either upon a screen frame or upon a sash frame without any alteration in form of the operator itself.

Accordingto the-prior art and practice, sash operators have beensuppqrted in various ways upon the sills of window frames in a manner to beattached to a related sash topermit adjustment of the sash by the operator. Operators so supported offer many disadvantages particularly in cases where window screens are to be mounted upon the sash frame on the inside face or room side thereof. Various methods have been devised to permit operation of a sash operator with a screen in position uponthe inside of the sash frame. A common, but cumbersome and expensive, method is to support-the operator on the casement sill and provide an opening or recess in the lower screen frame member through which the operator may be adjusted. Such, methods offer many disadvantages and are not susceptible of practical operation in the event that a side hinged screen is used.

Accordingto my invention,.I provide a screen frame which is formed in a manner to permit a sash operator to be-detachably mounted on the screen or, if desired, to be detachably mounted upon the related sash frame, and in either case no modification of the screen frame or operator is necessary. The practicaladvantage of these two optional forms of supports, is that a standard form of screen frame and operator may be used, wherein the operator may be supported entirely upon the screen frame while in use with the screen or the operator may be removed from the screen and secured to the sash frame, thereby permitting complete removal of the screen from the sash frame; or, inthe event that it is desired to mount a screen upon the sash frame with the operator in position on the latter, the standard form of screen frame disclosed herein may be adjusted, opened or closed, without interference providing a predetermined form of recess in the screen frame, and providing an operator having a corresponding form in side elevation together with means for securing the operator either within the screen recess, or upon the sash frame, and in the latter case, the recess in the screen frame is adapted to fit closely around the operatorwhen the screen is in its closed position,

In the drawing which discloses a preferred formof the invention, r f V Figure l is a view showing a screen frame and related operator with the screen in closed'posie tion and wherein the operator may or may not be secured to the screen frame;

Fig. 2 is a view in perspective of the operator itself; I

Fig. 3 shows the operator attached to afsash frame, the related screen frame being indicated by dotted lines in open position and by full lines in a closed position; and Fig. 4 shows the operator attached to thescreen frame, the frame being indicated by dotted lines in closed position and by full lines in an open'position.

For the purpose of illustration, I have shown a sash operator 1 modified in a manner to be used in practicing my'invention. The operator bar 2 is pivotally attached to the casing 3 and the outer end of this bar is secured to a sash link 4 by .means of a pivot 5. A bracket 6 secured to the sash 7 is provided with a hook 8 which is detachably connectedto the link 4.

In order to facilitate attachment of the operator to either a screen frame or a sash frame, I prefer to provide a lateral extension 9 on the lower face of the casing 3 as best shown in Fig. 2, wherein the operator is shown as rotated ninety degrees from its position in Fig. 1. Two series of openings 10 and 11 are provided to permit the optional support in a manner to be described.

The lower screen frame member 12 is provided with a rectangular transverse opening or slot; 13 corresponding closely in shape to a vertical section through the operator casing 3 and its extension 9. 100

Figure 3 shows one optional support for the operator 1 wherein it is attached to the sash frame 14 by means of screws 15 which are passed through the openings 10 and engage corresponding tapped openings 16 in the sash frame. With 65 the operator so supported, when the screen is closed as shown by full lines, the slot 13 fits closely around the casing 3. When the screen is moved to a partly open position as shown by dotted lines, the casing 3 and bar 2 will pass, relatively, readily through the slot 13. It will be noted in this figure that the extension 9 is attached to the vertical front face of the sash frame 14 and entirely free from contact with any sill that may be provided for the casement frame. It is necessary only to provide corresponding screw holes in the extension 9 and sash frame 14.

When it is desired to mount the operator entirely upon the screen frame as shown in Fig. 4, the casing 3 is inserted within the slot 13 and screws 15 which may be the screws 15 removed, are passed first through openings 17 formed through the lower face of the member 12 opposite the slot 13, and then through the corresponding openings 11 which may be threaded or tapped to engage the threads of the screws 15'. In this manner, the casing 3 is securely attached to the screen frame member 1-2. If there is any tend ency for the casing 3 to rotate around the screw support, the upper end of the casing will engage and bind against the top of the slot 13, thereby taking excessive strain away from the screw support which is of practical advantage when an operating force is applied to the sash in a manner to'react against the operator casing 3.

It will be noted from the above description that a simple and economical as well as an optional support in two forms is provided. This new result is obtained with its many advantages by merely providing a slot in the screen frame corresponding to the form of operator casing selected, and the latter is modified to provide an extension which may be drilled to receive attaching screws selectively in either of two positions of support.

The operator support disclosed is particularly adapted for use with side hinged screens. With the operator attached to the screen frame, the bar 2 may be detached from the sash by means of" the hook 8 and the screen and operator may be swung as a unit upon the screen hinges. With the operator attached to the sash frame as shown in Fig. 3, the screen may be freely swung to its full open position. If so desired, the screen may be removed from its hinges and stored away during certain periods, and the operator may be changed from its position on the screen and placed upon the sash frame. The essential feature of this invention relates to the provision of means on a single operator adapted to afford a support therefor in two relations, in combination with a preformed screen frame comprising a slot that is adapted to either receive the operator when it is attached to the screen, or to permit the operator to pass therethrough when it is attached to the sash frame.

While I have disclosed a preferred form of my invention for the purpose of illustration, it is to be understood that various modifications thereof are contemplated such as may be embraced within the scope of the claims which follow.

What I claim is:

1. A screen comprising a frame member, said member being provided with an opening extending therethrough, an operating bar, a bracket for supporting said bar, said bracket in vertical cross section being shaped to fit said opening and means for detachably supporting said bracket within said opening.
